Spent 2 hours on this today. It looks like Outlook is only sending an  
Autodisovery request with the exchange/outlook schema, NOT the  
MobileSync schema. Horde is receiving the request, and answering  
correctly for the schema it is requesting. The problem is, this schema  
is not for configuring ActiveSync, but rather any one of the "native"  
exchange protocols (RPC, MAPI over HTTP, etc...). I have tried sending  
back the MobileSync configuration anyway, but OL still fails -  
presumably because it doesn't match the requested schema.

I have no idea if this is an intentional change on the part of MS or  
not. I know that they have phased out ActiveSync support for  
Outlook.com accounts because of perfomance issues and various other  
limitations.

Bottom line - We can't work around this issue since Outlook never asks  
for the correct configuration.
